Sarsii goes deeper down and has not been taken in less than 40 fathoms, while on the contrary 

 it has been captured near the Feeroes at a depth of 388. Sabinea hystrix was obtained off 

 Guadeloupe at a depth of 734, off the east coast of the United States in water of 353—888, 

 and south-west of Iceland even at 1912 fathoms; this species occurs thus at the greatest depth. 

 Sabhiea iiidica, finally, was taken from 218 fathoms upward.
